bracket 19 secured to-the rear of the carrier 12. The function of this spring 17 is to automatically pull the slide upwardly when the latter is released from the influence of mechanism which operates to force the same downwardly. The slide 15 has a lower horizontally projecting plate 20 secured 'to bracket arm 21 forming part of the said carrier or secured to the latter. The plate 20 performs the function of a plunger and carries a number of instrumentalities in the form of pick-ups 21 for engaging individual washers. The carrier 12 has a spring 22 attached to one side thereof and to the adjacent frame upright 55, and also attached to this carrier is a connecting rod '23 which.

passes through a slot 24 in the opposite frame upright 5 and is adjustably and movably attached ,orjswiveled, as at 25, in the upper forked end 26 of an upright rocking lever 27, the latter lever'being fulcrumed at its lowervend to an extension of theangle footfi, as at 28. i

A drive shaft 29' extends through the frame uprights 5 and carries on one end a worm wheel 30 in continual mesh with a worin'3-1 ona transversely extending powertransmitting shaft 32 mounted in suitable bear1ngs33 secured to and pro ecting 'out-. wardly from theoneframe'upright 5.

On the rear endof the shaft 32 is a pulley or analogous device 34 to which power from a suitable source is adapted to be trans- V mitted. .On the end of the shaft '29 opposite that carrying the Worm wheel 30 a cam 35 is lined and is of the face type, or has its outer face formed withta cam surface '36 including a low part 37 gradually inclining into a highpart- 38, and engagingthis cam at a suitable elevation above the lower ful' ing to draw thecarrier. over into face 36 is a roller 39 carried on the rear end ofv asuitable shaft 40 fixed to the lever 27 crumed end of said lever; The cam 35 operatiug on the roller 39 and through the connecting'rod 23 w1ll draw the carrier-l2 towards the end of the machine at which the cam is located against the resistance of the spring 22when the roller 39 engages the support 41 provided with a pedestal-42 adjustablyiniounted in a collar and opening 43 provided as apart of the table and formed in the kitten-the adjustment of the I pedestal and moldsupportor member 41 thereof being accomplished through a set screw or, analogous device 44. The support. 41 is so constructed'as to removably receive ajheel slug 45. In Fig. 40f the drawings the 'posithe support 41 is shownas carrying a single heel slug, but it is to be understood that such support 41 may be constructed to hold any desired number of such heel slugs; i The plunger plate 20 carrying the pick-up dcvices21 is adapted to be normally disposed over and above the moldsupport 41 and heel slug 45, as shown by Fig. 2, for the purpose of"automatically inserting in each heel slug a predetermined number of washers, certain 46 of the form shown in detail by Figs. 1,

sluralit r ofo enin 's 47 formed thereinwith lower shouldered or enlarged portions. 48, as clearly llustrated by Fig. 13, and the plate 46 has upper and lower circular seats 49 and 50 connected by straight slots 51, as shown by Fig, 12 in dotted and full lines, the lower seats or. circular recesses being adapted to receive the washers simultaneously from the feeding means primarily carrying the washers, and the seats or recesses 50 providing the release means for the washers when in engagement with the pickps 21 depending from the plunger plate'20. From the foregoing it will be understood that thelower receptive seats or recesses 49 are offset relatively to the delivery or release seats or recesses 50, and the terminals of the slots 51 to the left are disposed in central relation to the lower receptire seats or circular recesses 49 which also at the right terminate centrally with relation to the delivery or release seats or recesses 50. By this means overhanging shoulders 52 are provided between the seats or circular recesses 49 and 50,'so as to effect a straight sliding movement of each washer these jaws extendingupwardly through each seat or circular recess 49 and slightly converging towardstheir-upper free ends so as to bespacedapart a less distance at the upperend than at the lower portion'of said spring jaws. The distance between the il -I) lower portions of the spring jaws 54 is greater thanthe diameter at one of the washers shown in Figs. 6 and 15, the said, washers being of a standard size and golf cup-shape, that is't'o say, each ,has a central depression-556 and a surrounding flange yr- The distance between the upperrends eaversea the high part 3801. thefcam 35,.

'The movement of the carrier is so rapid that'the washers 55 areall instantly the heel slug 4:5. and all simultaneously in- .serted by :a further depressing unitary I movement of the pick-ups 21 into the rubber slug, as shown by Fig. .145. The rubber slugs in which the washers are inserted are preliminarily prepared prior to disposition on the mold support ll by having suitable openings .72 formed; therein andextending partially through the same as shown by Fig.

.14, the said openings being of less diameter than the maximum diameter of the washers 55 inserted thereimand after the washers are seated in these openings -of the slugs,

they are held with sufficient resistance to permit the ready withdrawal of the lower "tapered ends 60 of the jaws 58rand 59, the

1 said tapered ends at this time being closed in viewof the downward pressure exerted Jon thepick-upunitsv and the operation of the wedge pins 69 with relation to the 'upper' ends slot the jaw units asshereinbefore explained. The closure, or contraction of the lower tapered ends, 60 of the jaws 58 and 59"of the pick-up units permits the latter to be readily elevated to the normal,

position shown by Fig. 2 and ready for further operation in con unction with the plate 46, 'the elevation of thepick-ups 21 into normal position takingplaceimmediatelyprior to a further shifting of the car-= V between the table 10 and the table member "*rier 12'to the left through the operation of the -mechanism' including the cam and 'and roller. 39 ihereinbe'fore described.

' It is' obvious that means must be provided v for supplyingthe plate .46 with washers at regular intervals, and it is proposed to use any organ zation of dev ces adapted for.

this'purpose. One "preferred organization of cooperatlng devices, however,-1s shown in the drawings andparticularly byFigs-B, 4c,

"5, '10, 11, 13 and]l5. The essential. elementor this feedingmechanism is a reciprocatingrod "or elongated pin 73 upon which the washers are mounted, the washers all i being disposed with their concave sidesluppermost, and in the preparation of the ma-: v chine for operatiom'each rod or .pin 73 will be'filled uniformly to'the upper end thereon.

The number ofrods or pins 78- employed will be 'equalto the numberiof recesses or seats 49' and '50 formed in the plate 46, and

' theserecesses .49 and 50 as well as the'rods I ;,or' pins 73 may be yaried in accordance with e b5 [the number 'ofwashers desired to be inserted I in each rubber heel slug. The operation of --1,e11,oea

the rods or pins 73 must also be such that they will first elevatethe stack of washers spring jaws 54.- by each upward thrust of 7 .each of the rods or pins. It is also neces to provide means for compensating for the gradual diminution of the. number of washers 55 oneach rod or pm 73, and moreover, to provide foravariation, of thenumber of washers on each rodor pin so that there may be at all times a regularity of teed or delivery of the washers to the plate 46 and the spring jaws'54 of the latter. All of the "rods or pins 7 3 have a similar mounting. and operation, and a detail description of one will, therefore, sufiice for all. Ea'ch rod or pin 78 is secured to a reciprocating tube or tubular llOLlSlIlg' 74. by means of a removable screw 75, whichunder certain conditions will permit the rod or pin to be withdrawn from the tube.

The lower. ends or. the tube 74 is secured to a reciprocating support 7 6, the said lower end of thetube 74- extending fully through the support as shown by Fig. 15, so that each tube 74 may be movably mounted over a guidetube' 77.

secured at its lower end to an adjustingfoot plate 78. Eachtube 74 has free movement through an opening 79 formed in the table 7 I l0, this opening alsoreeeiving the lower end of a tubular upright 80, which' also engages-the lower shouldered or enlarged portion 480i one of the openings47'in the table member 4E5?- which carries the plate 46.

The plurality of tubular uprights 80. provide forthe necessary strength or rigidity 4-5, and at the same time serve as tubular housings for 'the'operation' of the tubes 74 and rods or pins 73 therethrough. The upper end of each guide tube 77 has a cenand the upper end of the tube 77 is a washer plunger consisting of a tubular shank 82' of reduced. diameter havingv an upper flanged head 83.011 which the washers are disposed,

the lowermost washer of each stack bearing on the said head 83. -The centrally 'apertured cap8 l at the upper end of'the guide tube 77 movesover theshank 82, but the lower end of this shank is. screw-threaded and has a retammggscrew collar or r ngnut 84 which prevents separation of the lower extremity. of the said shank 82 from the cap '81 and the'upper end of the guide tube 77. Surrounding the shank 82 is .a spring v 85 against the'lower endof which the cap 81 hasbeari'ng engagement, the upper end of V the spring engaging the'fianged-head'83 of vtheplunger. Thesprmg85provides for a 7 tw n cushioningoperation as e'll asan adjustment; to compensate for Variation of'the number of ,washer's that are supported by therhead 83 as the said Washers are gradu:

; ally fed-tothe jaws 54 above and in accord j ance Withwthe ad-jnstmentbf the foot plate 78; in a manner which Willbe presently 6X: plained. Thefguideytube, 777 has a longitudinal; slot 86 therein through -Whichthe screw 75: extends so, asto permit reciproca- 1' tion of the tube 77 and-the rod or pin '73 Without restriction. Thus, as the guide tube-77, through-its foot-plate 78, is gradu-. ally adjusted to compensate for a diminu-.

The irregular cam 115 has the greater portion thereof, as at 118, concentric with the shaft 29, and in alinement with one diameter ofthe said shaft the cam 115 is.

formed with a cam rib 119 extending full length thereof. In the opposite portion of the said cam 115 a high part or cam projection 120 is formed of suflicient dimen- 1 sions to provide for the motion which Will be presently explained and having abrupt side portions 121 continuing into the portions'118 concentric with the shaft 29. The

' cam 113 controls the reciprocation of the washer feeding mechanism and its change of movement relatively to the said feeding mechanism is accomplished through the .medium' of links 122 secured at their up- '-per ends to apertured bosses 123, one of which is shown by Fig-1O and secured to or forming part of the reciprocating support 76. The lower ends of the links 122 are connected to the arms 12 1 of the front bifurcated extremity .125 of a rocker arm 126-having an intermediate bearing 127 adapted to engage one of the tie rods 7. The rear end of the rocking arm 126 is enlarged and bifurcated, as at 128, and carries a roller 129 therein which is adapted to Contact with the periphery of'the cam 113.

into engagement with the spring jaws 1 and place a washer above each-pair of said spring jaws, as 'hereinbefore explained. J

After this placement, a lowering action of the reciprocating.support and parts associated therewith for vertical movement again ensues. The rotation of the pulley 9 on the lower end of the shaft or spindle 92 for actuating the screw-threaded feed sleeve. 96 is accomplished through the medium of a crossed belt 130 which is also trained over a pulley 131 mounted on a motion trans mitting shaft v132 having 'suitable bearing in angularly depending bracket arms133 secured to the rod 7 on which the rocker arm 126 is mounted. On the shaft 132 a band pulley 13 1 is also carried and is of materially greater diameter than the band wheel or pulley 131, the pulley 13 1 having a belt 135' trained ther'eover and over the pulley 114 on the shaft 29 between the cams 113 and 115. The proportions of this driving mechanism and the threads 98 of the sleeve 96 is such that one complete revolution ofthe.

shaft'29will feed the sleeve 96 vertically the distance of one thread and correspondingly raise the reciprocating support 76. The dis-- tance feed of one thread 98 of the sleeve 96 corresponds to the thickness of'one washer, V

and hence, as each washer is removed from the several rodszor pins 73, the compensat-io-n for difference Of'VBI'blCfll extent of the stacks of washers on the severalrods .or pins 73 is provided for by the screw-threaded ing the proportions or ratio of all of the.
